How do I remove the wiper blades from the wiper arms of an edge stang

 

bump

 

turn the blade to a 90degre angle with the arm in the poped up position and there is a little release pin on it then they slide right out....if i was by my car i could explain better.

edit:the little metal pin thing is flat and and points down twards the car when you have the arms poped up. push in in twards the arm and they slide right off
